corporation of ew Jersey Application January 19, 1942', serial 10.4213422 Cnims. (01.189-72) i The present invention relates to improvements inbus or car window construction, and particularly to the slide channelsor runways in which the vertical side edges of the window sash-areengaged for sliding raising and lowering movement. With this type ofsliding sash it is neces.

sary, in order to permit the sashto be operated 'with ease, while at thesame timeproviding a structure in which normal manufacturing tol'-erances are permissible, thatclearances be maintained between the parts,these clearances being normally sealed by means of suitable rubber andfelt sealing means. It has been found-that heavy rain forced against theoutside of bus window structures of this type, even in the case ofVstruc'- tures wherein great care has been takento produce a goodwindowseal with the window sill, when the window is closed, finds itsway through some of the small openings or spaces existing between someof the contacting 'and relatively movable members. Quite often'in doingthis, the rain water builds up in the space within the post pieceassembly back of the: vertical .side edge of the window sash, and intime this rain water builds up sufficiently to cause objectionable leaksthrough to the inside of the bus.

It is obvious that a sash made to t tightly into the'side channels orrunways would, of course, tend to reduce in size or eliminate some ofthe openings or spaces through whichrainrunder pressure would beadmitted to' the back inside portion of the runway, but such tightnesswould result in a sash that would be extremely difficult to raise andlower, and would furthermore not compensate for the expansionandcontraction effect of extremetemperature changes. Reducing tolerancesand overcoming sizeand crosssectional variations of parts and assemblieswould eliminate or reduce objectionable small openings or spaces, butthe manufacturing cost of such a structure would become prohibitive,4and furthermore the maintenanceA of a perfect t, when the window is inservice and subjected to'varying degrees of strain and rough treatment,would not be reasonably possible. 4

An object of the invention is to providey a'win- Atoward such drainopening and will be prevented from reachingparts of the assembly'whereby it could leak inside theA bus. f

A further object is to providedrain opening ythe sash is engaged.

Similar reference characters indicate corresponding parts throughout theseveral figures of the drawings.

Referring to the drawings, the window sash part of the bus or car windowstructure, in which the invention is incorporated by way of example,comprises a sash glass II) having a top rail (not shown), a bottom railII, and a pair of vertical side straps I2 connecting the top and bottomrails, only the lower end of one of these side straps being shown. Theside straps are adapted to have vertical sliding movement in thechannels or runways mounted on theside posts, hereinafter more fullyreferred to. Each of the side straps I2 is in the form of aU-shapecross-section channel and is adapted to receive the marginal sideedge of the glass, the vertical edges of the strap being bent outwardlyand rearwardly, as at I3-I3, to engage the edge of the U-shapecross-section strip of facing material I4, of felt composition or thelike, which is cemented or otherwise suitably secured upon the sidestrap, to adapt it to have easy sliding engagement in the side postchannel assembly.

At the lower end of the side strap I2 there is rigidly secured bywelding, or other suitable means, a right angularly extendingrectangular cross-section tubular member I5 about which is secured atubular sheath member I6, and which two tubular members constitute arigid securing bar member for securing the bottom rail II to the sidestrap, this bar member being insertable in the longitudinally extendingspace I'I of the bottom rail where it is rigidly secured by means ofscrews I8. One of these screws I8 may preferably be one of the screwsfor attaching the casing I9 of the latch member 20, which is connectedto a spring-pressed bolt member 2I, slidable in the tubular member I5and having its nose portion projected through a slot 22 in the strap I2and in the facing I4, this bolt member adapted to cooperate with therack in the channel assembly for supporting the window in adjusted openpositions, and being retractable by operation of the latch 20.

The bottom rail II is provided at its underside with a sealing stripattaching channel 23, having longitudinal inwardly bent flanges 24 ateach side, and in which is engaged in interlocking relation a rubbersealing strip 25 for engaging the window frame sill 26 in sealingrelation, the ends of this sealing strip 25 extending into verticallyaligned flush relation with the vertical end surfaces of the facingstrip I4 at each side edge, for the purpose of having sealing engagementwith a rubber sealing member carried in the channel assembly at eachside, as will presently more fully appear.

The channel assembly in which the window sash is slidably mounted iscarried upon the side post 2'I of the window frame in abutting relationagainst a vertically extending flange 28 provided at the inner side ofthe post, and which abuts against an upwardly projecting flange 29provided along the inner edge of the sill 26. The channel assemblycomprises a fixed inside stop member 30 having a vertically extendingforwardly bent base portion 3I and a forwardly disposed lip flange 32formed of double thickness by bending the metal ofthe lip flangebackwardly upon itself, as at 33, the edge of this backwardly bentportion being projected toward the side post 2'I. A strip of packing 34,which may be of felt, sponge rubber, or other suitable material, isengaged between the side post and the base 3| and projecting edgeportion 33 of the xed stop mem- I5 ber, the latter being secured to theside post by means of screws 35 engaged through holes in the base 3I andin the side post and screwed into retaining nuts 36.

The removable outside stop 31 is bent upon itself to provide an innerleg portion 38, disposed in spaced parallel relation thereto to form arecessed structure for straddling the lip flange 32 of the inside stop,the outside stop being provided at suitable intervals, preferably nearits upper and lower ends, with hook members 39, secured between itsouter and inner leg portions by spot welding or other suitable means,and which are adapted to be wedgingly engaged in bayonet slots 40provided in the lip flange 32 of the inside stop to thus secure themovable outside stop to the fixed inside stop. The outside stop isadapted to be xedly secured in its engaged position by means of a setscrew 4I carried in its outer side and adapted to be screwed into athreaded hole 42 in the lip flange 32.

Within the channel formed by the inside and outside stops there isprovided a rack carrying channel strip 43, preferably covered with astrip of facing material 44, of felt composition or other suitablematerial and cemented thereto, and provided at its forward side withinwardly bent flanges 45 which engage the backing strip I4 of the windowsash, the channel strip being yieldable pressed into engagement withthis backing strip by means of a series of bowed leaf spring members 46secured upon the base 3| of the inside stop by screws 41. Within thechannel strip there is provided a rack member 48 preferably welded inplace, and which is adapted to be engaged by the latch bolt 2I carriedby the base rail of the window sash. In the lower end of the channelstrip there is interlockingly secured a sealing block member 49, ofrubber or the like, which projects slightly beyond the flanges 45 of thechannel strip and is adapted to be tightly engaged by the end of therubber sealing strip 25 of the base rail in the closed position of thewindow sash.

In the lower end of the channel structure there is secured to the baseportion 3| of the inside stop member a block member 5l] preferablyformed of sponge rubber cemented in place, the inner vertical edge ofthis block member being engaged against and cemented to the innersurface of the inside stop and the outer forward vertical edge beingslightly spaced from the lip flange 32 to provide a recess in which theleg of the outside stop is adapted to be engaged. The upper surface ofthe block member is inclined downwardly from its rearward to its forwardedge. Adjacent the forward edge of the inclined upper surface of theblock member 50, there is provided in the lip flange 32 a hole 5I forthe purpose of providing an outlet drain passage for rain water whichmay collect in the channel assembly and which flows along the inclinedtop surface of the block member 59 toward the hole 5I.

The outside stop member is provided in its inner leg portion with acut-out 52 having its lower edge arranged to be substantially in linewith the forward edge of the inclined top surface of the block member 53in the engaged relation of the outside stop, and which provides apassage for the rain water to flow from the inclined surface to andthrough the hole 5I. The outside stop is provided at its outer portionwith a slot opening 53 formed by slitting the metal and thereuponpresssing the metal above the slot opening outwardly in the form of arounded hood 54, so arranged that the rain water flowing .through thehole I will flow against the ,inner side of the hood and be emitteddownwardly through the slot opening 53, the hood at the same timeprotecting the slot opening against entrance of rain water from theoutside. 'Ihe slot opening 53 is arranged substantially above the sill26 so that back-wash and splash upon the sill will not ow into the slotopening.

In Fig. 15 there is illustrated a modified form of the invention inwhich the water drainage means is incorporated in a channel assembly ofthe type in which the outside stop is fixed and the inside stop isremovable. In this case, the side post 2'!a is provided adjacent itsouter side with a vertically extending abutment flange 28EL againstwhich the outer portion of the xed stop 30 is engaged, the lip flange 32upon which the removable stop is engaged being disposed inwardlyadjacent the flange 29 of the sill. The outer portion of the fixed stopis provided with a slit 53EL having a pressed out hood portion 54a aboveit, in similar manner to the slit and hood of the first embodiment ofthe invention, the upper inclined surface of the rubber block member 50having its lower end substantially in line with the slit 53 and theforward vertical surface of the block being secured by cementing to theinner surface of the outer portion of the fixed stop. The rearwardvertical surface of the rubber block member 50 is spaced forwardly fromthe lip fiange 32 to provide a space for receiving the inner leg 38 ofthe removable stop. The structure and operation of the channel assemblyis otherwise similar to that of the first embodiment.

I have illustrated and described preferred and satisfactory embodimentsof the invention, but it will be understood that changes may beV madetherein within the spirit and scope thereof, as defined in the appendedclaims,
